HONOLULU (AP) - Leaving behind a year of bruising legislative battles, President Barack Obama enters his fourth year in office having calculated that he no longer needs Congressto promote his agenda and may even benefit in his re-election campaign if lawmakers accomplish little in 2012.

Absent any major policy pushes, much of the year will focus on winning a second term. The president will keep up a robust domestic travel schedule and aggressive campaign fundraising and use executive action to try to boost the economy.

Partisan, down-to-the-wire fights over allowing the nation to take on more debt and sharply reducing government spending defined 2011. In the new year, there are almost no must-do pieces of legislation facing the president and Congress.

The one exception is the looming debate on a full-year extension of a cut in the Social Security payroll tax rate from 6.2 percent to 4.2 percent. Democrats and Republicans are divided over how to put in place that extension.

The White House believes GOP lawmakers boxed themselves in during the pre-Christmas debate on the tax break and will be hard-pressed to back off their own assertions that it should continue through the end of 2012.

"Now that he's sort of free from having to put out these fires, the president will have a larger playing field. If that includes Congress, all the better," said Josh Earnest,White House deputy press secretary. But, he added, "that's no longer a requirement."

Aides say the president will not turn his back on Congress completely in the new year. He is expected to once again push lawmakers to pass elements of his jobs bill that were blocked by Republicans last fall.

If those efforts fail, the White House says, Obama's re-election year will focus almost exclusively on executive action.

Earnest said Obama will come out with at least two or three directives per week, continuing the "We Can't Wait" campaign the administration began this fall, and try to define Republicans in Congress as gridlocked and dysfunctional.

Obama's election year retreat from legislative fights means this term will end without significant progress on two of his 2008 campaign promises, an immigration overhaul and closing the military prison for terrorist suspects at Guantanamo Bay, Cuba.

Presidential directives probably won't make a big dent in the nation's 8.6 percent unemployment rate or lead to significant improvements in the economy. That's the chief concern for many voters and the issue on which Republican candidates are most likely to criticize Obama.

In focusing on executive actions rather than ambitious legislation, the president risks appearing to be putting election-year strategy ahead of economic action at a time when millions of Americans are still out of work.

Still, Obama and his advisers are beginning 2012 with a renewed sense of confidence, buoyed by a series of polls that show the president's approval rating climbing as Congress becomes increasingly unpopular.

They believe his victory over Republicans in the payroll tax debate has boosted his credentials as a fighter for the middle class, a theme he will look to seize on in his Jan. 24 State of the Union address.

Obama's campaign-driven, domestic-travel schedule starts in Cleveland on Wednesday, the day after GOP presidential hopefuls square off in the Iowa caucuses. He will also keep up an aggressive re-election fundraising schedule, with events already lined up in Chicago on Jan. 11.

Campaign officials say Obama will fully engage in the re-election campaign once the Republicans pick their nominee. He will focus almost exclusively on campaigning after the late summer Democratic National Convention, barring unexpected developments at home or abroad.

Among the issues that could disrupt Obama's re-election plans: further economic turmoil in Europe, instability in North Korea following its leadership transition and threats from Iran.

The president's signature legislative accomplishment will also come under greater scrutiny in the new year, when a critical part of his health care overhaul is debated before the Supreme Court.

Obama's foreign travel next year will be limited mainly to the summits and international gatherings every U.S. president traditionally attends. He's expected to travel to South Korea in March for a nuclear security summit and to Colombia in April for the Summit of the Americas. He's also likely to visit Mexico in June for the G-20 economic summit.

Two other major international gatherings—the NATO summit and the G-8 economic meeting—will be held in Chicago, on home turf.
